It will now'beseen that the thread '18 permits the member B to be secured within an "opening in a boiler. V This is accomplished by the use of a squared wrench in-.

serted in the socket 18. The union nut '15 must be slipped then assembled as shown in Fig. 1. It will \Vhen the-valveis closed byrotating" the hand wheel to the right the reverse' occurs. I The valve rotates; in its seat until the play inthejoint is taken up and the spindle can rotate no farther. It will'be seen that we can rotate the valve in its seat a pre-determined distance beforeit opens and after it closes which keepsitconstantly ground to a place and prevents extraneous matter coata member 21 substantially as descrlbed.

ing or collecting on the valve or its seat.

. It will be particularly noticed that a support guide-31 is now provided; The spindle member 21 rotates in the opening 15} and "{LlSOflIl the guide 31 which retains it in alinement sothatthe valve. will take its seat evenly and operate with the spindle member 7 21'- The member 21Hhaving openings 7 'near its end only, makes it stronger; The f rectangular shape of this part of the memher also allows its corners 80 tosorape the surface of the opening 19 keeping it free of scale. It will also be seen that the adjacentparts can'be all removed while'the member B issecured to the boiler with the valve in place on the spindle part 21 under pressure.

The interior .of the part 21 can then be easily cleaned as well as all remaining parts of the valve body, and spindle. This is apparent because of the larger spaces afforded for access, the securing of the body together by the union'nut and the socket which permits the member 13 to be secured in a boiler copies of this patent may be obtained for without injury 'to or disarrangement of 'otheraparts.

It has been demonstratedby actual. experience that the spindle member 21 must havesufficient metal and be formed to insureresistance to twisting, bending or breaking if an: attempt is made to operate the valve. In the present device the steam or fluid passes, as will beseen upon opening the valve, through the openings 30 and .lthrough the spindle members 21 and 22, thence through-the openi gs 23 and the outlet-9. 1 In this device, the grinding of the valve in its seat is absolutely insured and it can be always turned therein evenxthough 7 fast with scale. This is accomplished by the directtransmission of, motion to it with parts'and the changed forms as shown.

1. A gage-cockhaving therein a spindle comprising two members 21-21, the latter having the female part of a T joint on one end longitudinal recess extending from the joining end a suitable distance with lateral openings therein, meansto retain the member 21 within the gage-cock in rotatable and longitudinally movable L position, the member 21 being provided with an integral valve on one end and the-male member of a T joint on its opposite end of a formto allow a longitudinal play between said members when joined, said member openings from said recessnear the valve,

also having a longitudinal recess extending from its ]O1I1l11g 6Ild to its valve, and lateral and a'support-guide formed and adapted .to. 1
